1,Automation: The frequency value of the signal generator is divided into 4 ranges, automatic switching, high accuracy, and all parameters will be automatically saved after setting, so it will not be lost when power is off. 2,Prevent Misoperation: The signal generator has a locking function to prevent misoperation and ensure that the value you set will not be easily changed. 3,LCD Display Screen: The signal generator has an LCD display, which shows the frequency and duty cycle value, and the reading is very convenient. 4,Strong Function: The signal generator has a PWM output function, the frequency and duty cycle can be set separately through buttons, and supports serial communication. 5,Wide Application: The signal generator can be used as a square wave signal generator for experimental development and motor driver, and can also be used as an adjustable pulse generator for MCU, control related circuits.
